In one embodiment, a method determines a first size of a first unit of video used for a prediction process in an enhancement layer. The enhancement layer is useable to enhance a base layer. The method then determines a second size of a second unit of video used for a transform process in the enhancement layer and determines whether adaptive transform is to be used in the transform process based on the first size of the first unit and the second size of the second unit where the adaptive transform provides at least three transform options. When adaptive transform is used, a transform option is selected from the at least three transform options for the transform process. |
